    • The present disclosure provides a method, device and system for implementing emergency call override service; wherein the implementation method comprise: a first application server (AS) on a called side receives an initial request message, carrying a service identifier indicating an emergency call override service, from a second AS on a calling side; and the first AS implements the emergency call override service according to the service identifier. In the IMS network architecture, by adding a service identifier, indicating emergency call override service, in an initial request message based on SIP, an AS network element on a called side can implement emergency call override service according to the service identifier, thereby solving the problem that the emergency call override service cannot be implemented in the current IMS network architecture.
    • 本公开提供了一种用于实现紧急呼叫覆盖服务的方法,设备和系统; 其中所述实现方法包括:被叫侧的第一应用服务器(AS)从主叫侧的第二AS接收携带指示紧急呼叫覆盖服务的服务标识符的初始请求消息; 并且第一AS根据服务标识符实施紧急呼叫覆盖服务。 在IMS网络架构中,通过在基于SIP的初始请求消息中添加指示紧急呼叫覆盖服务的服务标识符,被叫侧的AS网元可以根据服务标识符实现紧急呼叫覆盖服务,从而解决 紧急呼叫覆盖服务不能在当前IMS网络架构中实现的问题。
